THE ROLE OF CELL MEMBRANE STRUCTURE IN CELLULAR RECOGNITION

T细胞活化可导致IL-2和IL-2的释放 白介素2受体的表达。在人类中至少有两个 组成这种受体的链。在大鼠体内，有4种蛋白质可以 与IL-2结合，共同形成高亲和力受体 IL-2生长信号的传递。IL-2受体(阿尔法链) 在活化的T细胞培养上清液中以可溶性形式存在，在 感染性和炎症性疾病患者的血清和脑脊液。这个 多发性硬化患者脑脊液IL-2R水平显著升高 硬化症。流感疫苗研究表明，疫苗对 肠外联合鼻腔注射产生抗体的研究 使用灭活疫苗和减毒活疫苗进行免疫。

Activation of T cells results in the release of Interleukin-2 and the expression of the Interleukin-2 receptor. In humans there are at least two chains that comprise this receptor. In rats there are 4 proteins which can bind IL-2 and together they form the high affinity receptor necessary for the transmission of the IL-2 growth signal. The IL-2 receptor (alpha chain) can be found in soluble form in activated T cell culture supernates, and in serum and CSF from patients with infectious and inflammatory illness. The CSF IL-2R levels are significantly elevated in patients with multiple sclerosis. Influenza vaccine studies have shown additive effects on antibody production with the use of combined parenteral and nasal immunization with killed and live attenuated influenza vaccines.
